If you are only going to be shooting a couple of shorts I would look at just hiring gear and not buying. The only problem is that you can't hire the SI-2k (& Red) at the moment (you can't even buy them).
The price of buying a JVC will rent you fair amount of shooting time with a HDCAM or Varicam camera and maybe even a good lighting cameraman.

I don't know if you can get them down in OZ, but Gateway has a nice tablet pc that supports up to the t7400 Core 2 Duo and up to 4 gigs of 667mhz ram and several HD options. The screen is 14" diagonal at 1280x768 resolution. Has Cardbus, firewire and usb, gigabit ethernet, wireless and bluetooth.

If you go to their site, check out the CX210X tablet pc. You can customize it and have their system send you a quote (no salesperson involved). Only negative I found was no expresscard slot. I think the Mac Book Pros have those.

Guys, I hate to be a wet blanket on the enthusiasm but we have no way of testing on a lot of these alternate platforms. We test our software on Dell M90s, Precision 390s and our SI-2K motherboard. Those are the officially supported platforms. It *should* work on Core 2 duos at 2.33GHz, 2GB of RAM *but* it is not guaranteed.

Bummer, since I have no intention of buying a Dell. Prefer custom built system from a local supplier.

We are adding a powerful set of real-time look visualization tools which require advanced pixel shaders and texture processing which exceed the capability of current embedded graphics that are often found in the small form factor tablets.
